How to convert teaspoons to tablespoons
tablespoons = teaspoons ÷ 3
Example: 4 tsp ÷ 3 = 1 1/3 tbsp.
Divide the teaspoons by 3. A whole result means you can swap in tablespoons, and any remainder stays as teaspoons.
12 teaspoons become 4 tablespoons. 5 teaspoons become 1 2/3 tablespoons, which you measure as 1 tablespoon and 2 teaspoons. Half teaspoons work the same way: 7 1/2 teaspoons are 2 1/2 tablespoons.
With whole teaspoon counts, any leftover is one or two teaspoons, so you never need a partial tablespoon measure. To go the other way, see tablespoons to teaspoons.
US vs UK teaspoons and tablespoons
In the UK, Canada and New Zealand the spoons are metric, 5 ml and 15 ml, and you still divide by 3. The US teaspoon is 4.93 ml, so for a few spoonfuls either set gives the same result.
Australian tablespoons are bigger. At 20 ml, each one holds 4 teaspoons, so 8 teaspoons of spice make 2 tablespoons in Australian terms, not 2 2/3.
For an Australian recipe, then, divide teaspoons by four instead of three before you reach for the big spoon.
| Unit | Size | Used in |
|---|---|---|
| US teaspoon | 4.929 ml | US |
| metric teaspoon | 5 ml | UK, Australia, Canada, New Zealand |
| US tablespoon | 14.79 ml | US |
| metric tablespoon | 15 ml | UK, Canada, New Zealand |
| Australian tablespoon | 20 ml | Australia |
When do teaspoons add up to tablespoons?
Scaling up is where this conversion saves the most scoops. Doubling 1 1/2 teaspoons of baking powder gives 3 teaspoons, which is exactly 1 tablespoon.
A seasoning blend shows the savings best. Made six times over, a mix with 1 teaspoon each of cumin, paprika and garlic powder needs 2 tablespoons of each spice: six scoops in all instead of eighteen.
Write the new amounts down before you start measuring. It is easy to lose count after the fourth or fifth scoop.
Teaspoons and tablespoons: questions
Is a teaspoon bigger than a tablespoon?
No, the tablespoon is the bigger spoon. It holds 14.8 ml, against 4.9 ml for a teaspoon, so it carries three times as much of any ingredient.
Is 1 teaspoon half a tablespoon?
No, it is a third of one. You need 1 1/2 teaspoons for half a tablespoon, so a single teaspoon falls short by half a teaspoon. In a halved recipe, that gap matters most for salt and baking powder.
How many tablespoons is 2 teaspoons?
2 teaspoons equal 2/3 tablespoon. Measure it as two level teaspoons rather than trying to fill a tablespoon two thirds of the way, which is hard to judge by eye.
How many tablespoons is 10 teaspoons?
10 teaspoons are 3 1/3 tablespoons. Measure 3 tablespoons and add 1 teaspoon, which takes four scoops instead of ten. Fewer scoops also means fewer chances to lose count.
How many tablespoons is 18 teaspoons?
18 teaspoons make 6 tablespoons. That is also 3/8 cup, so a 1/4 cup measure plus 2 tablespoons does the job; see teaspoons to cups for larger counts.
